Patriot National Bancorp Announces Second Quarter Earnings of $0.16 Per Share

Loans Grow 9% Since Prior Quarter

STAMFORD, CT – July 29, 2016 (GLOBE NEWSWIRE) – Patriot National Bancorp, Inc. (“Patriot”, “Bancorp” or the “Company”) (NASDAQ: PNBK), the parent company of Patriot Bank, N.A. (the “Bank”), today reported net income of $614,000 for the second quarter, or $0.16 diluted income per share. This is compared to $689,000 a year ago, or $0.18 diluted income per share. In the first quarter of 2016, the Company reported $653,000 net income, or $0.16 diluted income per share.

As of June 30, 2016, total assets have increased to $653 million (up 2.7%), compared to $636 million at March 31, 2016 and $629 million at June 30, 2015. Net loans totaled $523 million (up 9%) at June 30, 2016 compared to $480 million at March 31, 2016 and $489 million at June 30, 2015.

Kenneth T. Neilson, President and CEO stated, “Growth has, and will continue to be, our primary focus. We have spent the last few years building a solid banking infrastructure, which has given us the foundation to confidently go forward with building our brand, hiring and training additional staff, creating and delivering a best-in-class customer experience, and showing by doing in the communities we serve.”

Michael Carrazza, Chairman said, “We continue to look for opportunities to better leverage our infrastructure and improve our returns.”

Net interest income before provision for loan losses decreased by $43,000, or less than one percent, compared to the first quarter of 2016 and decreased by $67,000, or 1.2%, as compared to the second quarter of 2015. The decline in net interest income this quarter, over the prior year’s second quarter and the current year’s previous quarter, is the result of a decrease in loan prepayment fees as the trend of fewer loan prepayments continues. Patriot’s loan portfolio actually increased by $43 million during the second quarter. The loan pipeline remains strong and continued growth is expected. Patriot’s net interest margin was 3.69% for the second quarter compared to 3.76% in the prior quarter and 3.73% in the second quarter of 2015.

No provisions for loan losses have been recorded since the first quarter of 2015. The credit quality of our portfolio and continued improvement in regional economic trends has allowed us to avoid increasing reserves. The Company has now experienced seven consecutive quarters of net loan recoveries.

Non-interest income decreased by $45,000, or 11%, over last quarter and by $86,000, or 19%, over the same period last year. Fewer loan fees in the second quarter of 2016 were the primary cause of these decreases.

Non-interest expense in the second quarter of 2016 decreased $28,000, or 1%, compared to the first quarter of 2016 which is on target with the Company’s business plan. Compared to the second quarter of 2015, non-interest expenses declined by $23,000 as a result of continued cost control.

Deposits were $449 million (up 5.4%) at June 30, 2016 compared to $426 million at March 31, 2016 and $457 million at June 30, 2015. Deposit growth initiatives are in place to increase deposits.

As of June 30, 2016, shareholders’ equity was $63.1 million compared to $62.3 million at March 31, 2016 and $60.1 million a year ago. The Company’s book value per share was $15.94 at June 30, 2016 compared to $15.75 at March 31, 2016 and $15.19 at June 30, 2015.

The Bank’s capital ratios continue to be strong as the Bank maintained its “well capitalized” regulatory status. As of June 30, 2016, Tier 1 leverage ratio was 10.13%, Tier 1 risk based capital was 11.21% and total risk based capital was 12.16%.
